A matrix is a rectangle of numbers in rows and columns. A 1xN matrix has one row and N columns. An NxN matrix has N rows and
N columns.
Multiplying a 1xN matrix A and an NxN matrix B produces a 1xN matrix C. To determine the Nth element of C multiply each element
of A by each element of the Nth column of B and sum the results. Helpful information can be found at matrix multiplication.
Write a program that reads a 1xN matrix A and an NxN matrix B from input and outputs the 1xN matrix product, C. The first integer
input is N, followed by one row of N integers for matrix A and then N rows of N integers for matrix B. N can be of any size >= 2.
For coding simplicity, follow each output integer by a space, even the last one. The output ends with a newline.
Ex: If the input is:
2
23
12
34
A contains 2 and 3, the first row of B contains 1 and 2, and the second row of B contains 3 and 4. The first element of C is (2 * 1) +
(3 * 3), and the second element of C is (2*2)+(3 * 4). The program output is:
11 16
Note: Store matrices A and C into one-dimensional arrays and matrix B into a two-dimensional array.
